Since its foundation in 1999, GST CO.,LTD have been focusing on the development of welding bellows, the core of the vacuum industry and secured technology to compete with the world's leading companies. Using thin plate forming and fine welding technology, we succeeded in developing V-bellows suitable for bellows seal valves and seamless bellows applied to high-purity gas valves and sensors for the first time in Korea. We are reborn as a bellows general maker by expanding our capabilities all in the field. In addition, based on excellent technology, we are supplying domestic and foreign large semiconductor, LED and solar related manufacturers, industrial valves, automotive sensors, and the aerospace industry that requires particularly high reliability. GST CO., Ltd. is making ceaseless efforts to make products that meet the diverse needs of customers with the motto of “more precisely, faster, and more inexpensively”, and is doing its best in research and development to become the best company in the field of vacuum components. Truly appreciate for your interest in our company and products.
Formed bellows are used in various fields such as refrigeration and air conditioning, electric power equipment, automobiles, aerospace, nuclear power, vessel, various valves requiring airtightness, vacuum piping, and pressure.
The double-layered LD bellows can prevent the release of toxic gas to the atmosphere in advance by checking for damage by adopting a sensor that can be identified with visual and an immediate notification in case of damage.
